When an event is published, described in
Publishing and Delivering Events, the
Broker will assign the event an event identifier that you can use to determine whether two events are exactly the same. You can also use the event identifier to match events with trace events or activity traces, described in the
webMethods Broker Administration Java API Programmer’s Guide. An event identifier is almost certainly unique. It is possible, though extremely unlikely, for two
Brokers to generate the same event identifier.
